Abstract

PURPOSE:To prevent the generation of an unreasonable compression force between a following roller and a cam which rolls in interlocking with the following roller and prevent the generation of vibration and noise, in a parallel index cam device in which the contour of a cam is shaped small in the vicinity of the recessed part of the cam and a preload is applied. CONSTITUTION:A locking cam 4, etc. are installed on a camshaft 2, and following rollers 17, 17a, 17b, etc. which contact the locking cam 4, etc. are installed on the spider of a spider shaft 3. The cam shaft 2 and the spider shaft 3 revolve as shown by the arrows 23 and 24, and in the vicinity of the part where the following roller 17b passes through the line connecting the center of the camshaft and the center of the spider, the pressure angle between the following roller 17 and the cam 4 is nearly 90 deg., and the contact force is increased. Since the cam is designed in condideration of the preload, the contact force is reduced. Thus, the generation of the noise and vibration due to the abnormal increase of the contact force can be avoided.

(Problems to be Solved by the Invention) In the conventional parallel index cam device, when each follower roller passes on a straight line connecting the camshaft and the spider shaft midway between the two axes due to the rotation of the camshaft, The pressure angle between the knot roller and the cam contour is 90''. Examples include the follower roller 19 in Fig. 1, the follower roller 17b in Fig. 3, and the follower roller 17b in Fig. 6. Therefore, in these conditions, , there is no place for the preload to escape, and a large compressive force acts between the follower roller of the spider and the four parts of the locking cam.If the preload is large due to this compressive force,
There were problems in that it generated vibrations and shocks, making rotation unsmooth.
